Abstract

RECENTLY, Doisy and his co-workers (1931) have reported the isolation from the urine of pregnancy of a crystalline substance possessing Ostrus-producing activity, which is distinct from the active substance theelin, previously described by them. The latter substance, to which they gave the formula C18H21(OH)2, was shortly afterwards isolated by one of us (Butenandt, 1929)1 and by Dingemanse and co-workers2 (1930). It was shown afterwards (Butenandt, 1930) that this substance is represented by the formula C18H22O2, and that it behaves either as a hydroxy ketone or as a dihydroxy alcohol.
